Results not correct #345

Open gianfrancoquartaruolo opened 1 year ago

gianfrancoquartaruolo commented 1 year ago

I need an help. When I load the TR maps I don’t find a correlation with results summarised in the table.

moreover, TR15 and TR30 differ a lot.

Is there a way to set up the software to have realistic results?

RT15 and RT30 can different depending on the room configuration but also if the echogram is too short to calculate the RT with accuracy (not enough dynamic): https://i-simpa-wiki.readthedocs.io/fr/latest/room_acoustics_parameters.html#reverberation RT maps are calculate using surface receivers (2D small plane surface, while for punctual receiver it is calculated using the energy in a spherical volume; it may explain some difference between the two calculation, but it should on the same order.

Could you give some us graphical results? Please use the Discussion tab instead : https://github.com/Universite-Gustave-Eiffel/I-Simpa/discussions
